Mage Manual - Chapter 506 - 414: Shiny and Sparkling

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

When a boy in a medieval fantasy world wakes up with the memories of his past life, he discovers a secret buried deep within his mind—a highly advanced AI companion. This AI, a relic of his previous existence, holds the knowledge of a futuristic world filled with technology, science, and innovation.Armed with this unprecedented advantage, the boy embarks on an extraordinary journey to transform his medieval surroundings into a thriving futuristic utopia. From reinventing agriculture to creating advanced cities, he introduces ideas far beyond the comprehension of his peers. But his vision isn't without challenges—power-hungry nobles, skeptical commoners, and ancient magical forces stand in his way.

No system, pure time travel, relying on intelligence and knowledge to control the situation, do not enter if you do not like it.-----------------------The protagonist travels to the Republic of France and becomes a quasi-rich third generation in a family of agricultural tractors.Unfortunately, it is near Paris. The Germans will soon come here, and to preserve the family, France must be saved.Gallieni: “God, the enemy actually presented their flank to us!”Xia Fei: “This can't be true, could it be a trap?”Protagonist: “The food is ready, go ahead, do I need to feed it to your mouth?”German Army: “Is this a tractor factory? What are these steel monsters that are impervious to knives and guns?”

Dying and then meeting a giant God in the image of an Impostor from Among us in the afterlife was certainly something I didn't expect would happen.Getting reincarnated by it, was something I expected even less.And awakening in a world where heroes and villains run rampant, was certainly the cherry on top on this whole matter.But well, nothing I can do about it.
